With the R2 ETAP introduces an extensive LED series of surface-mounted and suspended luminaires with diffuser. The R2 offers comfortable lighting (UGR ???? 19) in a contemporary luminaire, suitable for offices, hospitals, schools and representational spaces. Thanks to its high efficiency and long service life the R2 is also a smart investment for the long term.
Diffuser luminaires represent an asset in the lighting of ofﬁces, schools and public buildings. Logical, as they provide clear, uniformly illuminated spaces and guarantee pleasant and comfortable lighting without glare. After the U2 recessed version was introduced earlier, ETAP now launches the R2, an extensive range of surface-mounted and suspended luminaires with diffuser.
The slim, seamless housing and the clear glass cover give the R2 series a fresh, contemporary look, which comes into its own in any building. The series consists of square and elongated surface-mounted and suspended luminaires, which can be connected to clean light lines.
Comfortable and efficient
Traditional diffuser luminaires often compromise on efﬁciency to maximise comfort. However, the R2 combines comfort with out-standing performance, thanks to a combination of medium power LEDs and high-quality diffuser foil. The internal reﬂector with highly reﬂective paint and clear glass plate also contributes to optimal efﬁciency. These characteristics deliver speciﬁc luminous ﬂux up to 140 lm/W, thus limiting the number of luminaires to be installed.
The high-quality LEDs guarantee high lumen retention. You will still retain 98% of the initial luminous ﬂux (LLMF 98%), even after 50,000 burning hours.
R2 is a slimline, elegant luminaire with a superior ﬁnish. The diffuser with glass plate is ﬁtted in a steel plate housing, ﬁnished with matte structure paint. At the top the housing narrows around the LED plate. This component comes in black as standard, which provides the luminaire with a slimline and recognisable design. In the suspended version the fabric cable is also black.
A sensor for daylight-dependent control or motion detection, or an LED module for emergency lighting can be discreetly integrated into the housing’s narrow rim.
Ease of installation and maintenance
R2 luminaires are easy to install. First the ceiling module has to be installed, which also contains the driver. In the surface-mounted version the luminaire is secured to the module by means of brackets. Use the suspension set for the suspended version. If you mount the luminaires in line, one electrical connection is enough per line. Through wiring takes place through the driver housing.
The smooth cover plate on the R2 luminaires is made of clear glass and is easy to clean. The luminaire forms a single compact and closed unit, where dirt is kept at bay. Furthermore, the optic housing is ﬂy-proof.
The R2 range provides a suitable solution for every application or space. Individual or in line, square or rectangular, surface-mounted or suspended, the choice is up to you. The R2 suspended versions are available with uplight, with clearly lit ceilings as a result. The R2 series can be further adjusted to your needs with the various colour temperatures and luminous ﬂux (up to 5,500 lm).
